[Alt-photo] Re: choice of paper for Pt and gum over Pt prints - wasRe: Re: Replacement paper for Arches Aquarelle

I think Don was specifically asking about your choice of wording:
siderotype. To me siderotype is a shorter portmanteau term for all the
iron/iron-silver processes, whether or not they're any of Mike Ware's
processes  - I believe you've used this term exactly in that meaning.

Loris.
